To all whom it may co" cm:

Be it known that '1} DAVID C. LAMB, a

I citizenof'tlie United States of America, and

a resident; of Nappanee, in the State of In-' ,to portable electriclights, and consists in,

.The present invention relates exclusively an improved support, of astandtype, and

at the same, time conveniently"self-attaching, provided with a cord takeup and with means for varying at will the angle at which the lamp bulb,with or without a superposed shade or reflector, is supported all ashereinafter particularly describedand claimedi; B Two sheets of drawingsaccompany this specification as part thereof.

Figure 1 is an elevation of the improved device, in full and dottedlines, showing-different adjustments of-the same as used on a table orthe like; Fig. 2 is a bottom view projected from Fig. 1; Figs. 3 and 4are small scale views of the same device show-' 'ing it. respectively ashung on a nail and as attached to a rod or the like with the lampindi'iferent positions; Fig. 5 is an elevation at right angles to Fig.1; Fig- 6 represents on the lines, C -D and EF Fig. 6 respectively; Fi 9is a perspective'view of the a vertical section on-the line AB;.'Fig.'5; Figs. 7 and 8 represent horizontal sections reel detac ed t-and Fig.- 10 is'a fragmentary section showing the reel brake andits Likereference characters refer to like parts in all the figures.

' The iinproved devicecomprises a recessed coiled within an. upperrecess of said base, and" attached to said base at one end; a

wooden base a, a-superposed metallic reel housing I), fixedlyattached tosaid base by Wood screws,v a reel spring 0, Figs. 6 and 7,

cord 'reel, d, and a hollow spindle, 0, thereieaiss aei b Peie ts telesaesbrake, f, with its screw pivot, g, and spring h, Fig. 10, and a hingedtubular. stem preferably and. conveniently composed of lower and uppermembers i, j, with a. frictional hinge joint lathe axis of which ishorizon- A tal; said lower memberbeing coupled endwise to said "9 'I idle e and said upper member to a commercial lamp socket Z, which in turnreceivesfa commercial lamp bulb, m, while the latter supports a shade orreflector n adjustable as to position thereon or removable at will asshown Fig. 1.,

Aconductor-inclosing cord, o, of any re-' quired length, extends fromaplug, 79, Fig. 1, through openings- 1, 2, 3, in one side of the housing'b,-; in' the hollow hub of the reel d and at .a corresponding pointinthe:

spindle e within said hub, respectively, into said spindle, andlengthwise within the'latter and said tubular stem members 2' and j; itsbifurcations extending loosely around the stem of the hinge joint. andthrough the upper stem member j to the respective terminals withinthesocket Z. I v

. Thereel spring a being preferably and convenientlya fiat coil ofribbon steel, engages a longitudinal slit, 4, Fig. 9, in the lower endof the spindle e, and tends to keep the cord 0 wound upon the reel d;

When the required length of the 'cord 0 is drawn out from within thehousing I) through its aperture 1' the reel 01- is automaticallyfastened against the-retraction of the cord by the brake/ or interactionwith this brake the reel d has upperand Patented Dec. 22, 1914.-

lower horizonta disks, .5 and 6,-Fig. .9, of

different diameters, suitably spaced apart 'by the hub member of thereel, the upper I disk 5 clearing the brakef, which is pivoted. withinthe housing "6' at one side as shown inFigs. 6 and 10, while theperimeter of the -lower disk 6 projects radially beneath the brake f,and is efl'ect'ively engaged v by a curuedcamming surface'l', Fig. 10,at 1.00

the lowerend of the brake, underthe action the brake spring'h, Fig. 10..The reel is released for the retraction of the cord by tilting the brakelever f on its pivot screw g, by finger pressure on its upper end orfinger piece 8, Fig. 10, which protrudes top of the housing 6.

The base a is preferably and conveniently 1'05 upwardly through a'slot9, Fig. 10 the right-rod or bar, r, Fig. 4, and-other like objects. inthe manner set forth in said previe ous specification (Patent No.1,105,083) that is to say its bottom,'l3ig. 2, is provided with'atransverse groove, 10, within which a resilient member in" the. form ofa normally straight fiat bar, Z)", is fastened at midlength. by a woodscrew-1l; the ends of said ban protruding and 'being'provided with rigidarms a and a" parallelv with each *other,

adapted 'to'engage the bottom of said table top, shelf or'the like 9.asin dottedilines 'a' and a" in Fig.1, or said rod or bar',i"as-' inFig.4, so that the same is clamped y the resiliencyofsaid bar 5 againstthe bottom'of. said base.-.a,, said bottom being fur ther providedpreferably with a felt'cushion,

'12, said armsa "and'a" with cushioning sleeves, 13, of rubber tubing,and said'bar 20 b with edge cushions, 14, of fiat rubbenas described insaid previous specification; A reinforcing leaf, spring, represented ats in Fig. 2', is clamped into engagement withsaid bar bf by said screw11. A hole, 15, Figs-2 and 3, orIits equivalent, at or near one edge ofthe base a,conveniently provides for? Y hangingthe device on'anail,t,'or the like, as

represented in Fig. 3.

When thus hung against a wall," or when attached to anup right rod orbar-as Fig. 4, it is especially advantageous to be able to turn 'thestem member Lion the axis of the hinge joint Z0 so that the light bulb mhangs down as in dotted lines in Fig. 4:. The hingejointfis al soadvantageous when the device is used on a table or the like as in Fig. 1for adjusting the light; bulb m and its said superposed shade orreflector n with reference to a book or the like, and so as to suit andprotect the eyes of the user. Such shade or reflector n is preferablysubstantially hemisphericalin shapeiand provided with a pair ofcircularly curved resilient wires, 16 and'1.7, Figs.

'1 'and:5', between which the light bulb m is lightly and at. the sametime securely clamped, so as to form, in connection with the bulb m, auniversal joint of ample scope.

. The cord 0 and plug 7) may be of known or improved construction. Theirdetails and those oftlie socket Z, lamp m, shade or reflector n,attaching devices (a, a", b, 8) and the frictional hinge joint 70, formno part of the invention hereinafter claimed.

These details obviously admit of numerous immaterial changes; andotherlike modifications will suggest themselves, to those skilled in the art.The term wooden as herein used is intended to include materials"equivalent to wood, such as solidified plastic compounds.

Having thus described said improvement, I- claim as my invention, anddesire to patent under this specification:
